Error: Cannot find a file named pyalea_c.so
by Niraj Ghimire 13 Aug '14

13 Aug '14

Dear alps users, I was able to build ALPS and everything worked except that I got one error when I used the command "make install." The error message reads: CMake Error at lib/pyalps/cmake_install.cmake:42 (FILE): file INSTALL cannot find "/home/guest/buildalps/lib/pyalps/pyalea_c.so" where guest is my user account and buildalps is my build directory for ALPS. I have no idea what this file (pyalea_c.so) is and why I am getting this error. Please help me. Thanks, Niraj

REQUEST
by Niraj Ghimire 12 Aug '14

Dear alps users/developers, I humbly request you to write stuffs on the ALPS webpage, especially on the "Build ALPS from source" section, in a clearer/nicer way. For linux and alps beginners, it's sometimes difficult to understand what different command lines (e.g., cmake -D Boost_ROOT_DIR:PATH...., cmake -DCMAKE_INSTALL_PREFIX...., etc.) do and how one can really use them. Please elaborate every step so that even beginners don't spend too much time to understand what they are doing.… [View More]

underflow error reading the file
by Georgios Zavitsanos 12 Aug '14

12 Aug '14

Hello, I am trying to run my first example using ALPS code for Ising model... So, reading the tutorials, I wrote the parameter-input- file (parm1a), I converted to the file parm1a.in.xml and then I tried to run the command: spinmc --Tmin 10 --write-xml parm1a.in.xml but, I received the error message: basic_filebuf::underflow error reading the file . I installed the ALPS packages before one week, so maybe there is something new in writing the input files ? Any ideas would be very helpful... … [View More]

Building alps from source
by Niraj Ghimire 08 Aug '14

08 Aug '14

Dear alps users, I have been trying to build alps from source on Fedora 20 and I am having issues. I am new to alps and Linux OS itself, so I am spending too much time. I followed the instructions on "Get dependent libraries and tools on Fedora 20" and that was easy to understand and work out. Now I am on "Build ALPS". Either the instructions on "Build ALPS" are not sufficient for a Linux beginner like me or I am not being able to follow them. Please provide me with detailed … [View More]

site dependent potential
by benoît grémaud 07 Aug '14

07 Aug '14

Dear All, If I got it correctly, to have a site dependent potential one can use the inhomogeneous lattice and specify 'mu' as a function of space. However, it seems to be restricted to alps-defined functions (including rand()), but I couldn't find a list of them. For instance, is there a delta-kronecker function or a step function available? As an alternative, is there a way to pass a well defined set of numerical values? For instance to tune the boundary chemical potential only, I had to … [View More]

Question on multi-orbital PAM simulation
by Žiga Osolin 29 Jul '14

29 Jul '14

Dear ALPS community, I am trying to check if DMFT(QMC) calculations are consistent with my DMFT(NRG) calculations. I am working on Kondo lattice model (KLM), and I guess to simulate it with QMC, I have to consider PAM with correct parameters that translate to the KLM limit; the repulsion of f states should be high, U_f=8, on site energy e_f = -4 and hopping on the c states for example t=0.8. There is also spin-spin interaction J in KLM, here just the interaction between c and f orbitals, in … [View More]

dimerized chain
by Stone, Matthew B. 26 Jul '14

26 Jul '14

ALPS community, I am interested in calculating the states and the spin-spin correlation functions for a dimerized chain. This type of structure is sometimes called an alternating chain. It consists of spins coupled along one-dimension with alternating strong and weak Heisenberg exchange parameters: J0---J1---J0---J1---J0--- Using the tutorials and the ALPS website, I have assembled what I think are the correct UNITCELL and LATTICEGRAPH (see end of message). Q1: Is there a way to check … [View More]

Dear Prof. Troyer, There was no reply to problem of not being able to invoke vispython from the Cygwin command line: ENUKPERE@ENUKPERE-PC /cygdrive/c/cygwin/ALPS/bin$ vispython -bash: vispython: command not found How do I proceed?

Listed below are the instructions I followed along with what I actually did: Download a source package of ALPS: I downloaded alps-2.1.1-r6176-src.tar.gz <http://alps.comp-phys.org/static/software/releases/alps-2.1.1-r6176-src.tar…> (I was wondering if downloading alps-2.1.1-r6176-src-with-boost.tar.gz <http://alps.comp-phys.org/static/software/releases/alps-2.1.1-r6176-src-wit…> would be better). Create a build directory and execute cmake giving the path to the alps and to the boost directory: I unzipped the source package and tried using $ cmake -DCMAKE_INSTALL_PREFIX=/path/to/install/directory /path/to/alps/directory I don't know if I really understood this command line. But when I used it, I the error message "Cmake Error: The source directory does not appear to contain Cmakelists.txt" Thanks, Niraj On Wed, Jul 16, 2014 at 11:29 AM, Matthias Troyer <troyer(a)phys.ethz.ch> wrote: > Hi, > > You need to tell us more about where you get stuck if you want to receive > help. > > Matthias Troyer > > > > > > On Jul 16, 2014, at 7:44, Niraj Ghimire <niraj.ghimire(a)gmail.com> wrote: > > > > Dear alps users, > > I have been trying to build alps from source on Fedora 20 and I > am having issues.

INSTALLATION OF ALPS IN WINDOWS 7 32-BIT SYSTEM
by emmanuel enukpere 22 Jul '14

22 Jul '14

I have been trying to install ALPS in Cygwin in my Windows 7 32-bit system. After installing ALPS I got to the point where according to the instructions: "If, on the other hand, you install the binary ALPS package for MacOS or Windows you will need to download and install also Vistrails since the ALPS packages were built against the Python interpreter shipped with Vistrails. To do so call vispython " I tried to call as shown below with no success: ENUKPERE@ENUKPERE-PC /… [View More]
